    Abstract : Perovskite based materials have recently shown to have many unique properties that make them suitable for future electronic devices. In this thesis, the role of the interfacial microstructure on the properties of perovskite thin film heterostructures has been investigated. READ MORE

  5. 3. Growth and Characterisation of Non-linear Ferroelectric Heterostructures

    Author : Khaled Khamchane; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : High dielectric constant or ferroelectric materials are needed for a range of devices, non-volatile ferroelectric computer memories, NVFRAMs, microwave devices utilising the non-linear polarisation as a function of electric field, or other microwave applications. High dielectric constant and low losses can be achieved in single crystals of ferroelectrics. READ MORE

  6. 4. Characterization of (Ba,Sr)TiO3 thin films for multiplier applications

    Author : Pär Rundqvist; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; BSTO; THz; triplers; powerhandling capability; multilayer structures; frequency multipliers; Ferroelectric; BST; losses; Varactor; STO;

    Abstract : (Ba,Sr)TiO3 (BSTO) and SrTiO3 (STO) parallel plate ferroelectric varactors are investigated for microwave multiplier applications.STO and BSTO exhibit low losses, high permittivity and largetunability of both permittivity and losses. All films are deposited using Pulsed Laser Deposition, magnetron sputtering and E-beam evaporation. READ MORE
